Luxembourg leads the charge as youngsters bid to underline Classic credentials

The big coats are out, the wind is biting and the sun is getting ever lower in the sky, but dreams of high summer can still be grasped on Saturday with top-class Flat juveniles in stakes action across three countries and four racecourses.

Leading the way is Luxembourg, the unbeaten Ballydoyle colt who carries the increasingly familiar maroon and blue silks of primary partner and billionaire Georg von Opel, who could find himself contemplating Classic glory in next year's Derby if his exciting two-year-old captures the year's final Group 1 in Britain, the Vertem Futurity Trophy at Doncaster.

Luxembourg's trainer Aidan O'Brien last completed the Doncaster-Epsom double with Camelot, sire of his runner this weekend, although O'Brien's two most recent winners of the Vertem Futurity – Saxon Warrior and Magna Grecia – hardly let the team down by winning the 2,000 Guineas.
